Call Out - IBM 265 Service Manual

Surveillance takes effect immediately after the parameters are set from the service
processor menus.
If operating system surveillance is enabled (and system firmware has passed control to
the operating system), and the service processor does not detect any heartbeats from
the operating system within the surveillance delay period, the service processor
assumes the system is hung. The machine is left powered on and the service processor
enters standby phase, displaying the operating system surveillance failure code on the
operator panel. If call-out is enabled, the service processor calls to report the failure.

Call Out

The service processor can call out when it detects one of the following conditions:
v System firmware surveillance failure
v Operating system surveillance failure (if supported by the operating system)
v Critical environmental failures
v Restarts
To enable the call-out feature, do the following:
1. Have a modem connected to serial port 1 or 2.
2. Set up the following using the service processor menus or diagnostic service aids:
v Enable call out for the serial port where the modem is connected.
v Set the serial port line speed.
v Enter the modem configuration filename.
v Set up site-specific parameters (such as phone numbers for call-in and call-out

Although they can be used for paging, they return an error message when they
do not get the expected response from another modem. Therefore, even though
the paging was successful, the error message causes the service processor to
retry, continuing to place pager calls for the number of retries specified in the
Call-Out policy Setup Menu. These retries result in redundant pages.
